论文摘要
研究了近摩尼子对称性，以用于静态黑洞的溶液，这些溶液对包含超级翻译场的爱因斯坦方程。我们考虑保留度量标准的仪表和近摩尼子结构的一般差异性。差异是由矢量场产生的，并形成一组近马对称性。与度量标准的渐近级对称性相关的表面电荷变化的密度是在通过“大”转换连接的不同坐标系中计算的，这些转换会改变度量标准中的超倾斜场。在不同的坐标系中考虑了表面编术变化的整合性。详细研究了表面电荷整合变化的情况。
Near-horizon symmetries are studied for static black hole solutions to Einstein equations containing supertranslation field. We consider general diffeomorphisms which preserve the gauge and the near-horizon structure of the metric. Diffeomorphisms are generated by the vector fields and form a group of near-horizon symmetries. The densities of variation of the surface charge associated to asymptotic horizon symmetries of the metric are calculated in different coordinate systems connected by "large" transformations which change supertranslation field in the metric. Integrability of the variations of surfacecharge is considered in different coordinate systems. The case of integrable variation of the surface charge is studied in detail.
